resin coated sand as moulding sand of casting precoated sand
Description of resin coated sand as moulding sand of casting precoated sand:
TONTEN TM resin coated sand is a method in foundry practices and produces a casting of high precise dimensions, smooth surface, free of blow holes and devoid of casting defects.The surface of the sand is covered with a layer of solid resin film or sand. Cold and hot method of two kinds of coating process: cold method to dissolve the resin with ethanol, and in the process of mixing the mixture, so that the two covered in the sand surface, the evaporation of ethanol, Method to preheat the sand to a certain temperature, add resin to melt, stir the resin coated on the sand surface, plus aqueous solution and lubricant, cooling, crushing, screening coated sand. It is one of the best moulding sands for cars, tractors and hydraulic parts.
Characteristics of resin coated sand as moulding sand of casting precoated sand:
Low resin/High strength
Anti-Veining/Anti-Peel back/Super Low expansion
Anti-Peel back/Good Internal stiffening
super thin mass effect/good sand discharge
Benefits of resin coated sand as moulding sand of casting precoated sand:
Castings can be produced with close tolerance and with very minimum machining allowances along with excellent surface finish.
Self life of the resin coated sand is unlimited.
Hollow cores can be produced.
Lump free sand.
No crack of core or shell.
High transverse strength.
Low density of Raysons Resin Coated Sand gives maximum output.
Less core weight.
Release agent gives maximum output without breakages.
Fast curing of Raysons Resin Coated Sand gives high production with uniform baking of sand.
Special fine Resin Coated Sand doesn’t require refractory coatings or core paint, achieves better surface finish.
Low rate of gas generation.
Applications of resin coated sand as moulding sand of casting precoated sand:
lost foam foundry
